Offshore rock-socketed operation platform

Abstract

The invention provides an offshore rock socketing operation platform. The offshore rock socketing operation platform comprises a self-elevating operation platform (1), wherein four lifting pile legs (1.1) are mounted at four corners of the self-elevating operation platform (1); a hole drilling device (2), comprising a door frame which is of an opening-closing structure, is mounted on a deck of the self-elevating operation platform (1); pressurizing oil cylinders (2.5) are arranged on the door frame; pressurizing slide blocks (2.6) are slidably arranged in the door frame; the pressurizing oil cylinders (2.5) can apply a downward pressure to the pressurizing slide blocks (2.6); drilling rods (2.7) are vertically downwards arranged on the pressurizing slide blocks (2.6); drill bits (2.8) are mounted at the bottom parts of the drilling rods (2.7). The offshore rock socketing operation platform is high in construction efficiency and good in construction effect.

Description

technical field [0001] The invention relates to an operating platform for offshore operations, in particular to a drilling and piling platform for offshore construction, which can be applied to the fields of wind power and bridge pile foundations, and belongs to the technical field of marine engineering. Background technique [0002] At present, wind energy, as a clean and renewable energy, has been paid more and more attention by countries all over the world; its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the available wind energy is 2×10^7MW, The total amount of water energy that can be developed and utilized on the earth is 10 times larger; [0003] In view of the national conditions of my country's vast territory and long coastline, offshore wind energy resources are very rich and have great application prospects; and offshore wind power generation has the advantages of high wind speed, long effective power generation time, no land occupatio...

AI Technical Summary

Problems solved by technology

[0004] Most of the offshore wind farms that have been built today use a single-pile foundation, that is, a large-diameter steel pipe pile is directly driven into the seabed as the foundation of the wind turbine; the main advantages of the single-pile foundation are simple structure and easy construction. Convenience; to meet the needs of offshore operations, some companies have developed "a buoyant box-type positioning tool for piling offshore wind power foundations" disclosed in 201410186577.6, which adopts floating operation methods; however, with the rapid development of wind turbine manufacturing technology, single machine As the capacity continues to increase, the diameter of the required single pile becomes larger and larger, and the difficulty of seabed surface drilling, pile foundation hoisting and driving also increases; the above-mentioned tooling has been completely unable to adapt to the new operation requirements
